Embossing and seal press



UNITED STATES A PATENT OFFICE.

GEORGE B. SARGEN'I, OF BOSTON, MASSACHUSETTS.

EMBOSSING AND SEAL PRESS.

Specification forming part ot' Letters Patent No. 441,459. dated September 27, 1864.

To all whom it may concern:

Beit known that I, GEORGE. B. SARGENT,

\ of Boston, in the county-of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Embossing and Seal Presses; and I do herebyv declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanyin g drawing, forming a part 0f this specification.

The nature of my invention consists in so constructing and arranging the platen or bed of a seal o.: embossing press that it may be readily inserted in an envelope, in order that the lettering may be made only on one side instead of both, the back of the envelope being left untouched by the embossing-type, and the raised letters on the front of the envelope being more completely and uniformly formed than where it is necessary to emboss both sides at once, as it is with all the seal and embossing presses known or used before; and, again, where the embossing` is made through'twothicknesses of paper, (or both sides of an envelope,) when they are pulled apart one sheet is very apt to draw or tear the letters from the other, thus defacing or spoiling the work, leaving holes in place of letters, Whereas with my improvementthis defect is wholly avoided.

To enable others skilled in the art to make and use my invention, I will now describe its construction and operation.

The drawing is a full-sized'side elevation.

The principal parts of my press are like those in general use, A being the bottom of the frame; B, the goose-neck 5 G, the ver'- .tical cylinder, I, the cam lever, turning on the pivot J, and H the lifting-spring, whose upper inner end is fast to the top of the piston G. F is the female die, confined to the piston G in the usual manner, and E is the male die, soldered to the platen D. The upper side of the platen D is dat and of the usual shape. The under side, however,instead ot' extending down to the table X, (represented by the dotted lines,) asin other presses of the kind, is shaped as shown in the drawing, being beveled downward from the upper surface on the front and sides, so as to form a wedge-like arm, which, standing ont from the frame and above the table, can readily be inserted in an envelope, s0 that the front of the same shall alone receive the embossing.

The great utility and convenience of this construction and arrangement of the platen for the specific purpose of embossing envelopes, as described above, are obvious.

For other purposes my machine is precisely similar in operation to other seal and embossing presses in general use.

Costing no more than the common kind of embossing-presses, and performing, as it does, one entirely new and very useful function, I consider my invention a valuable improve ment in the art, and none the less for being exceedingly simple.

What I claim as new, and desire to secure by Letters Patent, is-

As an improvement in seal and embossing presses, so constructing and arranging the platen that it may be readily inserted in an envelope, substantially as and for the purpose described.

GEORGE B. SARGENT.
